Hehe, found a bunch of these in VIDEO_TS.VOB:

Didn't "investigate" though if they're accessible via some hidden button from the menus - like an Easter egg, I mean... ;-)

*difference between channels is -46.08 dB (0.50 %), resp. -50.51 dB (0.30 %)
**the scenes that were never dubbed into English have been left in Czech with optional English subtitles

This is a recording from ČT1 HD's digital satellite broadcast. Not considering the poor, bit-starved encode, nor the heavy cropping, the one thing I find interesting about it is the (at times significant) difference in colour timing; I can't possibly tell if this newer HD "scan" preserves the intended look and the who-knows-how-old master used for the 2002 DVD release is simply oversaturated, or if it's the complete opposite. However, being familiar with the DVD (can't honestly recall how this looked on the telly before the DVD appeared - never seen it on the big screen), I can't really say I like the "new" look...

The English menus / choosing the English dubbing default to the international version of the film.

Unlike Czech Television's broadcast, the Blu-ray resembles the older DVD quite closely - if it wasn't for the slight difference in geometry (observe the vertical lines in the shot of Tornado Lou on the stairs), I'd assume they both came from the same master.
     On the other hand, identical print damage (see e.g. the glowing spot in capture #4, or the horizontal scratch in #7 - not present in the broadcast version) points to at least the source film element being the same.

The 2 versions of the film are presented via seamless branching, the shorter one having the horrid VHS quality US opening title sequence tacked on at the beginning & similarly dismal looking end credits (0:14) at the... end. ;-)
